SEATTLE, March 15, 2012 /PRNewswire/ -- Omeros Corporation (NASDAQ: OMER), a clinical-stage biopharmaceutical company committed to discovering, developing and commercializing products targeting inflammation, coagulopathies and disorders of the central nervous system, today announced financial results for the fourth quarter and year ended December 31, 2011.

Financial Results

Total operating expenses for the three months ended December 31, 2011 were $11.0 million, compared to $9.5 million for the same period in 2010. The increase in operating expenses was primarily due to higher clinical trial expenses related to the Company's Phase 3 clinical program for OMS302. The increase during the quarter was also the result of higher expenses incurred in Omeros' GPCR program as well as one-time manufacturing and toxicology study costs intended to support clinical trials for Omeros' PDE10 and PDE7 programs. These increases were partially offset by lower costs related to the Company's OMS103HP program.

Total operating expenses for the year ended December 31, 2011 were $31.9 million, compared to $32.2 million in 2010. The decrease was primarily attributable to lower research and development expenses in Omeros' OMS103HP program and lower one-time fees related to its MASP2 program. Additionally, general and administrative costs decreased in part due to lower employee expenses and financing costs. These decreases were partially offset by higher costs related to Omeros' OMS302 Phase 3 clinical program, higher expenses incurred in the Company's GPCR program and one-time manufacturing and toxicology study costs intended to support clinical trials for Omeros' PDE10 and PDE7 programs.

For the quarter ended December 31, 2011, Omeros reported a net loss of $10.2 million, or $0.46 per share, compared to a net loss of $7.2 million, or $0.34 per share, for the same period in 2010. For the year ended December 31, 2011, Omeros reported a net loss of $28.5 million, or $1.29 per share, compared to a net loss of $29.3 million, or $1.37 per share, in 2010.

At December 31, 2011, Omeros had cash and cash equivalents and short-term investments of $24.6 million, compared with $42.0 million as of December 31, 2010. Omeros holds a $40.0 million equity line financing facility with Azimuth Opportunity, Ltd. Also, Omeros will receive an additional $3.0 million lease incentive payment in connection with its new office and laboratory space lease. Omeros expects that it has sufficient resources to fund operations for at least the next 12 months.

"Over the last few months, we have made significant strides across many of our programs. Most importantly, our first Phase 3 clinical trial for OMS302 met its primary endpoint maintenance of intraoperative mydriasis as well as the principal secondary endpoint of pain reduction in the early postoperative period, " said Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. "Our GPCR program continued to march through the Class A orphans having now unlocked over 40 percent, we expect to have screened all Class A orphans by the end of this year. Omeros' near-term milestones include completion of enrollment in our OMS103HP Phase 3 clinical trial for meniscectomy and in our second Phase 3 clinical trial evaluating OMS302. We look forward to reading out data from both trials in the second half of 2012."

Fourth Quarter and Recent Highlights

Reported positive data from its first Phase 3 clinical trial evaluating OMS302 in patients undergoing intraocular lens replacement surgery. OMS302 met its primary endpoint by demonstrating statistically significant (p<0.00001) maintenance of intraoperative mydriasis (pupil dilation). OMS302 also demonstrated statistical superiority (p<0.00001) over placebo in reduction of pain in the early postoperative period. The data for both endpoints are clinically meaningful. Omeros expects data from the second Phase 3 clinical trial evaluating OMS302 in the second half of 2012.

Secured a new 15-year lease for approximately 64,500 square feet of office and laboratory space in Seattle, Washington. Omeros will combine its office and laboratory facilities into this new space, which has been renamed The Omeros Building. In connection with this lease, Omeros will receive a lease incentive payment of $3.0 million.

Awarded a grant of $1.04 million from the National Institute on Drug Abuse (NIDA) to fund further drug development against neuromedin U receptor 2 (NMUR2). NMUR2 is a non-orphan GPCR linked to pain. Drugs that target NMUR2 could manage pain without the risk of addiction or other negative side effects associated with currently marketed analgesics (e.g., Vicodin®, OxyContin® and Percocet®) that target opioid and other pain-related receptors.
